Finally going to Japan next month!!!!! XD Im so excited! The chaos and fear has not hit me yet but I am full of excitement! I have a pile of ideas for stuff I want to do but have to organize and plan stuff out. Any tips, ideas, or info ya'll can suggest?

Really depends on what you're interested in, and where you're going to be hanging out.

Bringing cold medication with you is a good idea. You could catch something on the plane over, if not in Japan itself.

Most post offices will have an ATM that accepts foreign debit cards, but you'll be charged a bit for international withdrawals. They're only open until noon on Saturdays (and I haven't seen one open on a Sunday). In a pinch, you can go to the machines in 7-11's, which are open 24/7 and can give you cash advances on credit cards. Again, I'm pretty sure you'll be charged a fee for international transactions (even to view your balance).

I heard about a retro game bar called The A-Button somewhere in Akihabara. There was also a Dragon Quest bar in Roppongi (Luida's Bar), but last I remember you needed to get a reservation to get in because it gets packed. Good place to play Dragon Quest with other people, from what I hear.

If you've got friends with you, Pasera has a few karaoke joints in Akihabara. You might also check Good Smile Cafe's website to see if they have a themed cafe of something you're into when you go.

You're on Crunchyroll, so I assume you like otaku stuff. If you know Japanese, you can search for 聖地巡礼 and some anime show, and you'll probably find how to get to places that show was modeled after.

Mt. Fuji will be closed for general climbing until early July, so scratch that off the list unless you have alpine climbing gear and the experience to use it.

I blogged about my last trip around the Chuubu area (just west of the Tokyo region), so here's if you're interested. I got some long posts there, but you can just check out the map if you wanna know where I went.

Have a great trip and take a lot of pictures...Also, not sure if this applies, but if you are going to take pictures of the people over there make sure that you get their permission before snapping any pictures.

Other than that, have a great time and please post up pictures of your travels, I bet everyone here would love to see what you will (and have seen) over there.

Around Tokyo? Well, of course there's the Tokyo Skytree and the Tokyo Tower.

The Imperial Palace is always something to consider, but I don't think they allow general admission except on New Year's and the emperor's birthday. If I remember correctly, it's within walking distance of the Tokyo Tower, but you could take a tram if it's not.

The shrine at Asakusa, Sensou-ji, is a popular tourist destination. I honestly can't remember why it's historically significant. ^_^

Washinomiya Shrine in Kuki, Saitama is the shrine featured by the Kagami sisters in Lucky Star. Should be day trip material from Tokyo.

Nakano Broadway is another place like Akihabara. It's a little more expensive, but it's also easier to find rare things there. Or at least, it feels that way.

Toushou-guu in Nikko isn't too far from Tokyo. Tokugawa Ieyasu is enshrined there, and the Hear No Evil monkeys come from one of the decorations on the shrine here.

There's a Daibutsu in Kamakura (at the temple Koutoku-in) that's popular as a tourist destination. Ika-musume went here, and the series actually takes place at Yuigahama beach in Kamakura. Beach is closed until early July, though you might be able to walk around and take pictures.

Another large Buddha statue is in Ushiku - it's the third largest statue in the world, but it's out in the boonies and you have to take a bus to get there. The only other two larger than it are also Buddha statues.

Ryouhou-ji in Nishi Hachiouji is a temple dedicated to Benzai-ten. You might remember it from Crunchyroll News - they've moe-fied their temple and put out a... mobile game or something? There are other shrines to the fortunes around the area too (such as Bishamon-ten), some people visit them all (though only Ryouhou-ji is moe-fied).

Thanks for the support and ideas everyone! I think I am about complete with places and ideas now but still open to more. Thanks CaelK, I just added Nakano Broadway to my list. I had most of the others. Been doing hardcore research for week. Any good stores or restaurants to check out?

Can't really think of much you couldn't see by just looking through every nook and cranny. You'll probably run into them eventually, but some stores in Akiba, other than the obvious...

Super Potato - Retro gaming.
Yodobashi Camera - If you're into headphones, they have a good headphone section in the store, and you can audition them for free. I got to try an $8000 sound setup there, it was great.
Mandarake - They can stock some hard to find merchandise, so I usually like hitting them up at least once.
Trader - My general go-to for used games there. Three or four stores in Akiba.
Melon Books - I think this was in a basement in a building on the main street. Carries a lot of doujin stuff.
Messe Sanno - The one I remember, the spiral staircase down to the doujin section was kinda hidden in the back. Looks like a hardware store from what's in the first floor, if I remember correctly.
White Canvas - Come to think of it, when I went there last, they had a few pretty old doujin games.
Comic ZIN - Also carries some doujin, if you can't find it at the other places.

For Nakano Broadway, I just spent a day looking around everywhere I could find, so I don't remember specific stores. Mandarake was freakin' everywhere, though.

Also, there is a single Anna Miller's just outside Shinagawa Station's Takanawa exit. It's not a maid cafe, but I heard it was the model for some of the early ones. Maybe not the best food for the price, but it's not too Japanified. One of my friends is a fan, though.

OOhhh don't forget day trips man!! I just got back from Japan a few months ago, I go multiple times per year, I highly recommend heading out to Nikko, if you ever head back. It's a simple train ride from Asakusa on the Nikko Line takes about two and half hours but the ride is great. The town itself is just awesome your up in the mountains surrounded by trees it's very inviting. Hope you had a great time man!
